Mecistocephalus Tahitiensis
''Mecistocephalus tahitiensis'' is a species of centipede in the family Mecistocephalidae. This centipede is found in Australia and on islands in the Pacific. This species features only 47 pairs of legs rather than the 49 leg pairs usually observed in the genus '' Mecistocephalus''. Discovery and taxonomy This species was first described in 1862 by the American myriapodologist Horatio Wood. He based the original description of this centipede on type material found among the specimens in the collection of the Smithsonian Institution. The American biologist William Stimpson collected this material on the island of Tahiti in French Polynesia. In 1887, the German zoologist Erich Haase described a variety of this species found on the island of Viti Levu in Fiji and named this subspecies ''M. tahitiensis porosus''. In 1920, the American biologist Ralph V. Chamberlin deemed ''M. tahitiensis porosus'' to be a junior synonym of ''M. tahitiensis''. Since then, other authorities have ad ...

Species
A species () is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. It is the basic unit of Taxonomy (biology), classification and a taxonomic rank of an organism, as well as a unit of biodiversity. Other ways of defining species include their karyotype, DNA sequence, morphology (biology), morphology, behaviour, or ecological niche. In addition, palaeontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. About 14% of these had been described by 2011. All species (except viruses) are given a binomial nomenclature, two-part name, a "binomen". The first part of a binomen is the name of a genus to which the species belongs. The second part is called the specific name (zoology), specific name or the specific ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Zoology
Zoology ( , ) is the scientific study of animals. Its studies include the anatomy, structure, embryology, Biological classification, classification, Ethology, habits, and distribution of all animals, both living and extinction, extinct, and how they interact with their ecosystems. Zoology is one of the primary branches of biology. The term is derived from Ancient Greek , ('animal'), and , ('knowledge', 'study'). Although humans have always been interested in the natural history of the animals they saw around them, and used this knowledge to domesticate certain species, the formal study of zoology can be said to have originated with Aristotle. He viewed animals as living organisms, studied their structure and development, and considered their adaptations to their surroundings and the function of their parts. Modern zoology has its origins during the Renaissance and early modern period, with Carl Linnaeus, Antonie van Leeuwenhoek, Robert Hooke, Charles Darwin, Gregor Mendel a ...

Morphology (biology)
Morphology (from Ancient Greek μορφή (morphḗ) "form", and λόγος (lógos) "word, study, research") is the study of the form and structure of organisms and their specific structural features. This includes aspects of the outward appearance (shape, structure, color, pattern, size), as well as the form and structure of internal parts like bones and organs, i.e., anatomy. This is in contrast to physiology, which deals primarily with function. Morphology is a branch of life science dealing with the study of the overall structure of an organism or taxon and its component parts. History The etymology of the word "morphology" is from the Ancient Greek (), meaning "form", and (), meaning "word, study, research". While the concept of form in biology, opposed to function, dates back to Aristotle (see Aristotle's biology), the field of morphology was developed by Johann Wolfgang von Goethe (1790) and independently by the German anatomist and physiologist Karl Fried ...

Phylogenetics
In biology, phylogenetics () is the study of the evolutionary history of life using observable characteristics of organisms (or genes), which is known as phylogenetic inference. It infers the relationship among organisms based on empirical data and observed heritable traits of DNA sequences, protein amino acid sequences, and morphology. The results are a phylogenetic tree—a diagram depicting the hypothetical relationships among the organisms, reflecting their inferred evolutionary history. The tips of a phylogenetic tree represent the observed entities, which can be living taxa or fossils. A phylogenetic diagram can be rooted or unrooted. A rooted tree diagram indicates the hypothetical common ancestor of the taxa represented on the tree. An unrooted tree diagram (a network) makes no assumption about directionality of character state transformation, and does not show the origin or "root" of the taxa in question. In addition to their use for inferring phylogenetic pa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Karl Wilhelm Verhoeff
Karl (or Carl) Wilhelm Verhoeff (25 November 1867 – 6 December 1945) was a German myriapodologist and entomologist, specialising in myriapods (millipedes, centipedes, and related species) as well as woodlice and to a lesser extent insects. Biography Karl W. Verhoeff was born on 25 November 1867 in Soest in Westphalia, the son of the apothecary Karl M. Verhoeff and his wife Mathilde (born Rocholl). He completed his ''Abitur'' examination in Soest in 1889 and completed his doctoral thesis in zoology in Bonn in 1893. In 1902 he married Marie Kringer, who died in 1937 during surgery. The marriage produced three children, two daughters and a son, the son dying in 1942 on the Russian front. He was briefly employed (1900–1905) at the ' in Berlin, but for the remainder of his long career, he worked privately. Verhoeff undertook a number of collecting trips, including visits to the French Riviera, and Romania and Bulgaria down through Bosnia and into Greece. Some of these trips were ...

Papua New Guinea
Papua New Guinea, officially the Independent State of Papua New Guinea, is an island country in Oceania that comprises the eastern half of the island of New Guinea and offshore islands in Melanesia, a region of the southwestern Pacific Ocean north of Australia. It has Indonesia–Papua New Guinea border, a land border with Indonesia to the west and neighbours Australia to the south and the Solomon Islands to the east. Its capital, on its southern coast, is Port Moresby. The country is the world's third largest list of island countries, island country, with an area of . The nation was split in the 1880s between German New Guinea in the North and the Territory of Papua, British Territory of Papua in the South, the latter of which was ceded to Australia in 1902. All of present-day Papua New Guinea came under Australian control following World War I, with the legally distinct Territory of New Guinea being established out of the former German colony as a League of Nations mandate.

Mecistocephalus Porosus
''Mecistocephalus porosus'' is a species of centipede in the Mecistocephalidae family. This centipede was described in 1887 by German entomologist Erich Haase based on a specimen measuring 41 mm in length. He originally described this centipede as a subspecies of '' M. tahitiensis''. In 1920, the American biologist Ralph V. Chamberlin deemed ''M. tahitiensis porosus'' to be a junior synonym of ''M. tahitiensis''. Since then, other authorities have adopted the synonymy proposed by Chamberlin. Despite this proposed synonymy and the original description of this centipede as a subspecies, many references list ''M. porosus'' as a separate species. Distribution The species occurs in Fiji. The type locality is the island of Viti Levu Viti Levu (pronounced ; ) is the largest island in Fiji. It is the site of the country's capital and largest city, Suva, and home to a large majority of Fiji's population. Geology Fiji lies in a plate tectonics, tectonically complex area betw ...

Synonym (taxonomy)
In taxonomy, the scientific classification of living organisms, a synonym is an alternative scientific name for the accepted scientific name of a taxon. The Botanical nomenclature, botanical and Zoological nomenclature, zoological codes of nomenclature treat the concept of synonymy differently. * In nomenclature, botanical nomenclature, a synonym is a Binomial nomenclature, scientific name that applies to a taxon that now goes by a different scientific name. For example, Carl Linnaeus, Linnaeus was the first to give a scientific name (under the currently used system of scientific nomenclature) to the Norway spruce, which he called ''Pinus abies''. This name is no longer in use, so it is now a synonym of the current scientific name, ''Picea abies''. * In zoology, moving a species from one genus to another results in a different Binomial nomenclature, binomen, but the name is considered an alternative combination rather than a synonym. The concept of synonymy in zoology is reserved f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ralph Vary Chamberlin
Ralph Vary Chamberlin (January 3, 1879October 31, 1967) was an American biologist, Ethnography, ethnographer, and historian from Salt Lake City, Utah. He was a faculty member of the University of Utah for over 25 years, where he helped establish the University of Utah School of Medicine, School of Medicine and served as its first dean, and later became head of the zoology department.

Subspecies
In Taxonomy (biology), biological classification, subspecies (: subspecies) is a rank below species, used for populations that live in different areas and vary in size, shape, or other physical characteristics (Morphology (biology), morphology), but that can successfully interbreed. Not all species have subspecies, but for those that do there must be at least two. Subspecies is abbreviated as subsp. or ssp. and the singular and plural forms are the same ("the subspecies is" or "the subspecies are"). In zoology, under the International Code of Zoological Nomenclature, the subspecies is the only taxonomic rank below that of species that can receive a name. In botany and mycology, under the International Code of Nomenclature for algae, fungi, and plants, other infraspecific name, infraspecific ranks, such as variety (botany), variety, may be named. In bacteriology and virology, under standard International Code of Nomenclature of Prokaryotes, bacterial nomenclature and virus clas ...
